ABSTRACT
Objective To evaluate the changes of the left atrial function in patients with old myocardial infarction(OMI) by strain rate imaging(SRI). Methods The velocity of the left atrial lateral wall and atrial septum was measured by SRI in 30 patients with OMI(OMI group) and 25 normal subjects (control group). Left atrium passive eject volume index(LAPEVl) and left atium active eject volume index (LAAEVI) were measured using Simpson method. Results ①Compared with the control group, the velocity of the left atrium was reduced obviously in ventricular systole and early ventricular diastole in OMI group(P<0.05) ,but was increased in late ventricular diastole(P<0.05). ②Compared with the controls, LAAEVI was increased significantly in OMI group, but LAPEVI was decreased signicantly(P <0.001). Conclusions SRI could be used to evaluate the left atrial function accurately in patiens with OMI.
